106.05.08(一)14:00-16:00 IEEE特聘講座專題演講(電機系507R)

摘要：

    Theory, technologies, applications, and current R&D status of the wireless power transfer (WPT) will be presented. The talk will cover both the far-field WPT via radio waves, especially beam-type and ubiquitous-type WPT, and energy harvesting from broadcasting waves. The research of the WPT was started from the far-field WPT via radio waves, in particular the microwaves in 1960s. In recent years this became a hot topic again due to the rapid growth of wireless devices. Theory and technologies of antenna and circuits will be presented in case of beam-type and ubiquitous-type WPT. The industrial applications and current R&D status of the WPT via radio waves will be also presented. Antenna technology for the WPT will be mentioned. In order to increase beam efficiency from a transmitting antenna to a receiving antenna, which is almost 100%, the antennas must put on Fresnel region. We cannot use Friis transmission formula on Fresnel region. Special technology of the antenna for the WPT will be introduced.
